  • a wire to be described below may be a wire, which is a shoelace loop, added to the detachable lacing apparatus using a shoelace loop for footwear 100 .
  • the scope of the present disclosure does not need to be limited to one type of wire, and although it is collectively referred to as a wire in the claims of the present disclosure, it is natural that various materials and types of wire may be covered. That is, a wire 20 , which is a shoelace, may be formed from any of a wide variety of polymeric or metallic materials or combinations thereof that exhibit sufficient axial strength and bendability for the present application.
  • one or a plurality of lace loops 14 are formed, through which the wire 20 , connecting a plurality of shoelace holes 12 spaced up and down and facing each other, is connected in a crosswise form.
